' "MAsSAGEDEvioE.

'-" Be it'known th'atI, BENJAMIN S. DEAN, a

citizen of the-United States of America. and

a resident of Philadelphia, county of Philadelphia, Stateof Pennsylvania, have invented certain new and useful Improvements in Massage Devices, of which the following is a specification, reference being had to the acing the flesh or roller devices for merely rolling over .the flesh. In hand manipulation of flesh for massage purposes it is common to take up a pieceof-flesh between the thumb and the finger and work or knead the flesh by I working the thumb and finger backward and forward.

It is the main object of my present invention to produce-a'machine which shall as "closely as'possible imitate this hand manipulation of the flesh; and to this end I provide a plurality of massage members for grasping the flesh and means for so operating the members as to knead or work the flesh between them. v

- In the preferred form of my invention the gras ing members are rollers which rotate slow y in a direction toward each other, so as to pick up and hold the flesh, and I provide '35 means for imparting contravibrating movements to the said rollers while they are rotat- "ing, these contravibrating movements being very rapid relatively to the movement of rotation thereof and being through but a small arc of a circle. In a machine which I have' designed for this purpose and in which my invention is embodied the rollers rotate toward each other'at about the 'speed of one hundred revolutions to the minute, while oscillatory movements are simultaneously imparted thereto through one-eighth of a revolution two thousand times a minute, the said oscillations being in directions opposite to each other;

My invention also consists in many novel arts and features of construc'tion, which will oint out more clearly hereinafter, and in or er that my invention v Specificationof Letters Patent.

In the drawings, Figure 1 is a view in longitudinal section through a device embodying my invention, the plane of section being taken substantially upon the line 1 1 ofFig. 2.

Fig.2 is a view in transverse section thereon, the plane'of section being substantially upon the line 2 2 of Fig. 1.- Fig.3 is an end view of the device. Fig. 4 is a detail view showing a portion of a gear-wheel with its hub and a cam-slot therein, the same being a portion of the mechanism for transmitting the vibrating movements above referred to. Fig. 5 is a fragmentary view showing particularly the slotted condition of the box or housing which ermits lateral movements of the massage-r0 er shafts. Fig. dis a fragmentary view of one of the massageroller shafts.

The views are drawn to an exaggerated scale in order to better illustrate the device,

the device itself being considerably smaller than the device as illustrated.

- The massage members in the device herein ers shafts 7' and 8, carried by arms 9 and 10, connected to sleeves 11 and 12. The sleeves 11 and 12 are mounted upon a stationary arbor 5 and 6, mounted upon 13, secured to and carried by a box or frame 14. The sleeves 1 1 and'12 are mountedloosely upon the said arbor, whereby the rollers 5 and 6, carried by the arms 9 and lOsecured thereto, may move freely. backward and forward toward and away from each other. Springs 15 tend to press the saidrollers with a yielding pressure'toward each other, but

permit the said rollersto be forced apart against such yielding pressure.

The box or frame-su port'14 is provided with a handle 16,. by w -ch the device as a whole may be conveniently manipulated, and a drive-shaft 17 passes through the said handle from the BXtBIlOI. thereof to the interior of the said box. This shaft may be driven by any suitable meansas, for instance, by a flexible shaft connection with aunotor of any- I oo kind. At its end within the box the said shaft is provided with a drive-pinion 18,

which engages a spur-gear 19, loosel mounted upon the stationary arbor '13. hisgear conveniently has along hub, so that itmay have a long bearing on the said arbor, and the. said hub is also. employed for the purpose of supporting another gear-wheel 20,

which is rigldly fastened thereto. The, said gear-wheel v20 takes in with a spur gear221 upon the shaft 7, which carries the roller 5.

The shaft 7 penetrates to the interiorof the box for this purpose,

as shown in Fig. 5, whe're and the said box is conveniently slotted,

- the shaft so penetrates-it, in order to permit the swinging movement of the shaft above referred'to. Rotation of the shaft 17 then will impart alcontinuous r to the-saidiroller 5. The spurcar 19 has secured to the face thereof eve gear-teeth 22, which intermesh with a bevel gear-pinion 23, arranged to'rotate upon a stationary stud at ri ht angles to the axis of the arbor 13, the beveled ear-wheel 23 also intermeshing with another eveled gear-wheel 24,- mounted to turn loosely upon the hub of thespur-gear 19.-

The gear-wheel 24 will itself then rotate in a direction op osite to-therotation of'the spurgear 19, an a gear-wheel 25, (corresponding to the gear-wheel 20,)whioh is affixed to the I shaft 7, as shown by the arrows I arrows in Fig. 3, it will be seen that the rollersturn toward each other,

5 thegearing is so designed that the speed of I ,theform of an o lique disk, as shown, said secured transversel said beveled gear-wheel 24,

said hubs is mounted a collar 31.

lars 31 have flan it in a direction 0p osite to the direction of the said gear-whee 20. The gear-wheel 25 intermeshes with a'spur-gear 26, carried by the shaft 8, which carries the rollers 6, and movements of rotation will h'encelbe imparted to the shaft. 8 and'roller 6 opposite to the.

movements imparted to the roller 5 and in Figs. 2 and 3. It will be understood, of course,"that the box 14 is also slotted where'the shaft 8 enters the same as above described in connection with the shaft 7 Noting the direction of the and the ratio of such rotation shall be about one hundred times a minute, If these rollers be ap lied to the flesh, the tendency thereof will e to.-

draw the flesh up between them, the rollers slightly parting to permit the flesh'to ass between them without unduly pine 'ng same.

I will now describe the means for imparting the vibrating movements to the rollers, such movements being, it will be remembered,

preferably in opposite directions throughshort arcs and at a hi drive-shaft 17 is rovided with a cam 27 in projections 33 o the said frame 29, whereby the said collars 31 are gibratedbackward' and forward by the said frame in its vibration, itself vibrated" by thev thesaid frame bein cam 27, as above set fo'rth. Each of, the said rollars 31 is rovided with a pin 34', which passes throng 1 a the said i provided, and through a slot rotary' movement will rotate with h rate of speed. The;

slot 35,.with which each of.

36-, (see particularly Fig. 6, vwith which each 7 and 8- is provided. The slots,

ofthe shaft v I g in the said shafts are in line wlth the r axes,

and 26 are oblique. One of the SitldhllbS with its slot 25, is shown in dctail,F1g 4, and the correspondin slot for the hub of the other of thesaidw eelswillbe similar thereto,

the opposite direction; The reciprocating movements of the collars 31 will by reason of the pin-and-slot connection 'ust described impart relative movements 0 progressionand retrogression between the shafts and the spur-gears thereon, such movements constitutin ferre extending" through, complete revolution,

to. The "slots 35' are herejshcvnas aboutione-eighth of a so that the vibrating said-slots being in opposite directions the said vibratin movements will besopposite movements 0 a vibration or oscillation of the twoshaftsand -.rollers with respect to each "other. The shaft 17 isarr'an ed to'revolve at a very high rate of speed, t esamebeing gears 21 '26, so that such Qhiighrate of-speed-v of the-.drive -shaft will only e ect a compare-f The cam 21, however, bein rectly upon f the drivesshaft, t e speed of-the vibrating movements, will be"""eryh1gh, and

vibration is arrangedat about two thousand per minute when the iollers revolve at about one hundred revolutio s per minute. A de-' vice so constructed will roduce a massaging effect closely imitating he handmassage, the slow rotation of the iollerscausing the same to continuously grasp the, flesh when applied thereto, while the reciprocatingnor vibrating movements 7 the flesh in the most approved manner.

It will be obviousthat the one embodiment ,of my invention and that the same is capable of many and varied modifications within the invention, and, further, that certain parts may be employed in connection with other parts ofdifferent construction. Hence I'do not desire to be limited only to the precise details .of construction and combination arts herein;
